Shimano power meter on sale from November

This winter, Shimano is finally entering the power meter market with a Dura-Ace crankset, the $1,550 / £1,299 R9100-P. The dual-sided power meter will be available November 1 as complete crankset and will also be sold as just the two arms without chainrings.

While a few companies currently sell power meters based on Shimano cranksets — Stages created the left-arm category it now shares with Pioneer and 4iiii, plus brands like SRM and power2max have Shimano-compatible spiders — the Dura-Ace R9100-P is the first power meter from the Japanese component giant.

Shimano road product manager Dave Lawrence said Shimano decided to enter the power meter market largely based on feedback from pro teams.

“Teams wanted overall a very accurate, very consistent, very durable system,” Lawrence said. “We felt that since we are manufacturing the crankset, we could do that. We could install strain gauges at the time of production. We could bring all three of those pieces together. They felt like they weren’t necessarily getting that from their current options. They also wanted to be able to switch out chainrings very easily. And they also wanted left and right.”
